Dri-Lex Sockliner : Delivers heightened comfort through a moisture management lining system that is totally breathable and quick drying.

Heel Strap : Secure with a rip-and-stick closure to provide a secure, supportive fit; padded collars up the comfort level.

Insole, Polyurethane w Dri-lex® : A polyurethane footbed to provide plating protection and reduced packing over a sustained peroid of time, coverde with moisture-wicking material, Dri-lex®, for great comfort and cushioning underfoot, especially under the ball of the foot.

Insole, Stitch Polyurethane : Stitched into the shoe to protects skin and foot tissue for a more comfortable ride.

Instep Strap : Secure with a rip-and-stick closure to provide a secure, supportive fit with padded collars up the comfort level.

Polyester Fabric : A popular synthetic fiber that are extremely strong, durable (resistant to most chemicals, stretching and shrinking, wrinkle resistant, mildew and abrasion resistant) and are quick to dry. Able to retains its shape and hence is good for making outdoor clothing for harsh climates.

XS Trek Rubber : Vibram technical trekking compound that represents the world wide reference for this segment both for performance and durability. The grip is exactly what is needed from difficult trekking to multisport. Coupled with big lug sole design, it is possible to enhance traction and grip on demand. When used in at a low thickness, the feedback is communicative. The information about grip and geometry of terrain prevents slipping and tripping. Different hardness’s are available for this family of compounds to obtain a better compromise between performance and comfort.

Action/Reaction Techology™ : When using the ultra-efficient Land-Lever-Lift midfoot or forefoot running gait, the technology absorbs and then returns your own energy back to you. It's not fancy technospeak, and it's no gimmick. It's a revolutionary way of building a running shoe based on Sir Isaac Newton's third law of motion – "For every Action, there is an equal and opposite Reaction" Loosely translated, it means you get a boost of forward energy with every single stride you take.

Dual Density Media Post : Located at the medial midfoot to forefoot and is a higher density material engineered to slow the rate of pronation.

Met-Flex : A flex groove designed to allow the forefoot to flex naturally.

Metatarsal Sensor Plate : A sensor plate in the midsole to encourages a more natural spread of the foot within the shoe upon impact.

Midfoot Support Chassis : Chassis for added stability.

Universal Posting Technology : Is designed to accommodate runners who pronate, supinate and those with a neutral gait. This innovative midsole design features high-density X-shaped foam that supports both the medial and lateral sides of the foot. Working in conjunction with the Action/Reaction Technology and the Biomechanical Forefoot Top-plate, the Universal Posting Technology guides your foot down the center of the shoe. In the Newton Running shoes, the forefoot technology supports the bone structure of the forefoot ensuring even weight distribution and a solid platform for greater propulsion.

• Outsole •

Carbon Rubber Heel : Engineered for high mileage durability.

High Density Rubber : Utilized in the forefoot and is intended to provide a long lasting outsole.

Textured Outsole : Utilized throughout the shoe and is designed for additional traction.

WaveSpring™ : WaveSpring™ returns energy with every step.Ray Fredericksen, president of Sports Biomechanics, Inc. compares typical midsole materials found in many athletic shoes to running in sand. While initially perceived as soft and comfortable, these shoes require the wearer to exert greater effort. Muscles must work harder, causing fatigue and increasing the risk of injury.

Unlike traditional shoe midsoles made primarily of foams, rubber compounds, or polymers, WaveSpring™ technology stores and disburses energy with every step. Testing performed by an independent source reports that 87% - 96% of the energy is returned from the WaveSpring™. This is the highest energy return score for any midsole material ever tested.**

WaveSpring™ is light and compact.The WaveSpring™ is laterally stable, lightweight, compact, and can easily fit into a typical shoe midsole. The technology is in the heel and forefoot of the shoe. As such, it has the appearance of a normal shoe. Looking from the outside no one will know you have a spring in your step but you!

WaveSpring™ technology will not break down.Traditional midsole materials work through compression and often breakdown quickly. The WaveSpring™ is mechanical. The spring will outlast the shoe. The wearer will have a "new shoe" feel from the first day it is worn to the last!

DCS Plus® : Maximizes stability and cushioning with 2 interacting dual Cantilever® units. The top cradles the foot, while the bottom acts like a trampoline to soften the impact, stabilizing the foot and provide increased energy return. Fom(TM) technolory in the forefoot provides superior cushioning.

DCS Ultra® : Combines DCS with a TPU plate that provides torsional support in the midfoot; and a presurized air cushioning chamber in the heel.

Dura-Ryd™ Dura-Stryk™ : Stabilizes shoe with extended medial post and plate stability with Cantilever® outsole all designed to protect against overpronation.

Ecto Cantelever® System : Two specially designed plates work in unison to provide unsurpassed cushioning and stability. The top plate cradles the foot, while the bottom plate absobrs the impact of the heel strike.

FOM™ : Avia's soft and dense material located in key impact areas of the shoe. It conforms to your foot on impact for excellent cushioning and comfort. It bounces back to its original shape after each impact.
